“Editors on the English Wikipedia are currently investigating allegations of suspicious edits and sockpuppetry (i.e. using online identities for purposes of deception). At this point, as reported, it looks like a number of user accounts — perhaps as many as several hundred — may have been paid to write articles on Wikipedia promoting organizations or products, and have been violating numerous site policies and guidelines, including prohibitions against sockpuppetry and undisclosed conflicts of interest. As a result, Wikipedians aiming to protect the projects against non-neutral editing have blocked or banned more than 250 user accounts.” (via Wikimedia blog)
